Sennheiser HD 650 Studio Headphones

The Sennheiser HD 650 excel in mixing audio with plenty of spacial information across a wide range of frequencies. In an open-back design, dynamic drivers with highly-efficient neodymium magnets and aluminum voice coils are positioned quite far from the ear to provide a vast soundstage with incredible imaging and separation.

People tend to praise the HD 650 for their articulate low end that is punchy and full without crowding up too much of the mix as to compromise the mids or highs. There is a narrow valley at 70Hz before they slope down to 10Hz, leaving plenty of room for manipulating sub frequencies.

Starting at 90Hz is a wide peak that brings forward all of the upper bass and entire mid-range. This area is extremely revealing and detailed, allowing for excellent mixing of kick drums and bass elements to sit complimentary to one another. The mids are smooth, rich, while remaining rather neutral. They offer extraordinary clarity and certainly do not fatigue after hours of use.

The highs are sometimes accused for being a bit veiled as they have some peaks and valleys and roll off a bit too soon for some. We tend to agree, however this does not seem to serve poorly after mixes are played across multiple listening devices. They still offer a profoundly lush presence and an overall well-balanced sound.

The Sennheiser HD 650 do certainly fit like a luxury product. The replaceable over ear velour earpads fit snug with perfect pressure to fir securely for long sessions. They have a good balance of plastic to metal making them highly durable yet quite light at the same time. Plug them in via a detachable 3m long cable with proprietary connectors that connect on either side of the headphones.

It should be noted that the HD 650 have a pretty high impedance of 300 ohms which means they will require an amplifier or sound card with a decent preamp on their phones output for them to be really driven to their capacity. With a sufficient power source, the true revealing qualities of the HD 650 really stand out.

The Sennheiser HD 650 are ideal for engineers who work primarily in mixing and post-production with an eclectic portfolio. They serve extremely well for achieving top results in everything from hip hop to film scoring, and sound design to jazz. If what you’re after is a one-stop-shop kind of headphone that will get your mixes sounding great and at a very realistic price, then check out the Sennheiser HD 650 and discover why so many audio professionals call them THE headphones for mixing.
